Cardiac surgery is almost universally performed through a median sternotomy, an approach which is painful, unestethical, and prone to life-threatening infections. Minimally invasive cardiac surgery has tried to avoid problems associated with full sternotomy for many years. Recently, uniportal thoracic surgery was shown to be very advantageous when compared to standard thoracotomy and classical video assisted thoracic surgery (VATS). Despite very good results in lung surgery, cardiac surgery through a single thoracic port has rarely been attempted and successfully conducted...

Medical robots offer new standards and opportunities for treatment. This paper presents a review of the literature and market information on the current situation and future perspectives for the applications of robots in cardiac surgery. Currently in the United States, only 10% of thoracic surgical procedures are conducted using robots, while globally this value remains below 1%. Cardiac and thoracic surgeons use robotic surgical systems increasingly often. The goal is to perform more than one hundred thousand minimally invasive robotic surgical procedures every year...

Cardiac surgery is a relatively young specialty and is undergoing many changes presently. The advent of catheter-based technology, minimally invasive surgery and better information regarding the roles of cardiac surgery in the management of common cardiac disease is changing the way we provide services. In Australia, attention must be turned to the way cardiac surgical services are provided to enable delivery of modern procedures. This has implications for the provision of training. We explore the face of modern cardiac surgery and how this may be taken up in Australia...

Background: General anaesthesia and surgically induced changes in cardiac loading conditions may alter flow across the aortic valve. This study examined how echocardiographic assessment of the severity of aortic stenosis (AS) changes during surgery. Methods: Patients who underwent aortic valve replacement for any severity of AS between July 2007 and June 2015 were identified. Peak velocities, mean gradients, and dimensionless indices (DI) measured with preoperative transthoracic echocardiography (TTE) were compared with those measured with intraoperative transoesophageal echocardiography (TOE)...

Infrainguinal arterial occlusive disease can lead to potentially disabling and limb-threatening conditions. Revascularization may be indicated for claudication, rest pain, or tissue loss. Although endovascular interventions are becoming more prevalent, open surgeries such as endarterectomy and bypass are still needed and performed regularly. Open reconstruction has been associated with postoperative morbidity, both at the local and at the systemic levels. Local complications include surgical site infections (SSIs 0-5...

Ischemic stroke is a rare yet devastating complication that may occur following cardiothoracic surgery. Fibrinolytic treatment is contraindicated due to elevated risk for hemorrhage. Mechanical thrombectomy entails a catheterized approach wherein the thrombus is physically removed from the vessel without the use of fibrinolytics, minimizing the possibility of intracranial hemorrhage. Here, we present two original cases of mechanical thrombectomy as treatment for patients experiencing emergent large vessel occlusion following cardiothoracic surgery...

Iatrogenic injury to the circumflex artery (Cx) due to its close proximity to the mitral annulus is a rare but dreadful complication that can occur during mitral valve repair. The aim of our study was to compare multiple measurements of the Cx datasets, obtained by real time three-dimensional transesophageal echocardiography (RT3D TEE) and corresponding measurements assessed in multi-planar three-dimensional images acquired by multidetector computed tomography (MDCT). Preoperative RT3D TEE and MDCT datasets of 25 patients who had previously undergone minimally invasive mitral valve surgery were retrospectively analyzed...

A novel minimally invasive technique for left atrial myxoma surgery involving a combination of mini-sternotomy and restricted left atrial dome incision is described. Surgery is performed through a mini-J sternotomy at third intercostal space and a standard aorto-right atrial cannulation. Exposure of cardiac mass is obtained by a restricted incision of the left atrial dome which provides excellent view of the entire interatrial septum. Base of the tumor base is clearly visualized making the en-bloc excision extremely easy...

INTRODUCTION: Different techniques have been reported for the exploration and repair of femoral artery (FA) in patients who undergo minimally invasive cardiac surgery (MICS) and endovascular aortic surgery. We used a modified approach alternative to the conventional technique (group CT) since May 2013, which specifies a shorter groin incision and diamond shaped hemostatic purse sutures for arteriotomy closure without the requirement of cross-clamping (group PT) and evaluated early outcomes and the complication profiles of the two techniques for femoral access...

INTRODUCTION/AIM: Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) support is increasingly used in refractory cardiogenic shock and cardiac arrest, but is characterized by a rise in afterload of the left ventricle (LV) which may ultimately either further impair or delay cardiac contractility improvement. The aim of this study was to provide a comprehensive overview regarding the different LV venting techniques and results currently available in the literature. METHODS: A systematic literature search was performed in the PubMed database: 207 articles published between 1993 and 2016 were included...

Postoperative vasoplegic syndrome (VS) is characterized by low systemic vascular resistance, normal or elevated cardiac output, and poor response to volume expansion. The incidence of VS after cardiac surgery requiring cardiopulmonary bypass is about 20%. Sometimes, VS becomes refractory and initial treatments do not work, rendering treatment a great challenge. In this study, we describe a young male patient with endocarditis undergoing tricuspid valve replacement. When being weaned off cardiopulmonary bypass, the patient experienced VS...

BACKGROUND Primary cardiac tumors are rare but have favorable surgical prognosis. Previous studies have been small series studies with limited surgical approaches. To date, few studies have examined the clinical features associated with different surgical procedures. MATERIAL AND METHODS In a search of the cardiovascular surgery database of our institution, we retrospectively identified 225 patients who had cardiac tumor resection from January 1993 to May 2016. The patients' clinical characteristics and operation information were reviewed, and the operation parameters, postoperative complications, and short-term prognosis among robotic, mini-thoracotomy, and conventional procedures in our center were compared...

BACKGROUND: NSQIP Risk Calculator was developed to allow surgeons to inform their patients about their individual risks for surgery. Its ability to predict complication rates and length of stay (LOS) has made it an appealing tool for both patients and surgeons. However, the NSQIP Risk Calculator has been criticized for its generality and lack of detail towards surgical subspecialties, including the hepatopancreaticobiliary (HPB) surgery. We wish to determine whether the NSQIP Risk Calculator is predictive of post-operative complications and LOS with respect to Whipple's resections for our patient population...

Ischemic preconditioning has been utilized to protect the heart from ischemia prior to ischemia onset, whereas postconditioning is employed to minimize the consequences of ischemia at the onset of reperfusion. The underlying mechanisms and pathways of ischemic pre- and postconditioning continue to be investigated as therapeutic targets. We evaluated the administration of a delta opioid agonist or cariporide on various parameters associated with myocardial reperfusion injury upon reperfusion of isolated porcine hearts...
